URL of the codelab
Basic Android Kotlin & Compose: Classes and Objects

Task and Step where the issue can be found
The issue occurs during the interaction with the ellipsis (three-dot) menu in the codelab, specifically when it is clicked to display options.

Description of the Problem
When the page is viewed in Dark Mode:

The options in the ellipsis menu are not visible. The text appears black on a black background, making it impossible to read the options.
The page does not fully transition to Dark Mode, causing inconsistent styling and visibility issues.
Steps to Reproduce

Open the following URL:
Basic Android Kotlin & Compose: Classes and Objects

Enable Dark Mode on your device (if it's not already activated).

Click on the three-dot (ellipsis) menu at the top right of the page.

The options in the menu will be invisible due to the black text on the black background, making it unreadable.

Additionally, the page will not fully adopt Dark Mode, leading to inconsistent styling across the interface.

Expected Behavior

The options in the ellipsis menu should be clearly visible, with appropriate contrast between text and background, even in Dark Mode.
The entire page should seamlessly transition into Dark Mode, including all menus, buttons, and text.
